Engagement with indigenous peoples and honoring traditional knowledge systems
The organizers of the 2014 US National Climate Assessment (NCA) made a concerted effort to reach out to and collaborate with Indigenous peoples, resulting in the most comprehensive information to date on climate change impacts to Indigenous peoples in a US national assessment. Yet, there is still much room for improvement in assessment processes...Maldonado, Julie; Bennett, Bull; Chief, Karletta; Cochran, Patricia; Cozetto, Karen; Gough, Bob; Hiza-Redsteer, Margaret M.; Lynn, Kathy; Maynard, Nancy; Voggesser, Garrit
Two Holocene paleofire records from Peten, Guatemala: Implications for natural fire regime and prehispanic Maya land use
Although fire was arguably the primary tool used by the Maya to alter the landscape and extract resources, little attention has been paid to biomass burning in paleoenvironmental reconstructions from the Maya lowlands. Here we report two new well-dated, high-resolution records of biomass burning based on analysis of macroscopic fossil charcoal...Anderson, Lysanna; Wahl, David B.
Reconnaissance stratigraphic studies in the Susitna basin, Alaska, during the 2014 field season
The Susitna basin is a poorly-understood Cenozoic successor basin immediately north of Cook Inlet in south-central Alaska (Kirschner, 1994). The basin is bounded by the Castle Mountain fault and Cook Inlet basin on the south, the Talkeetna Mountains on the east, the Alaska Range on the north, and the Alaska–Aleutian Range on the west (fig. 2-1)....LePain, David L.; Stanley, Richard G.; Harun, Nina T.; Helmold, Kenneth P.; Tsigonis, Rebekah
Stratigraphic reconnaissance of the Middle Jurassic Red Glacier Formation, Tuxedni Group, at Red Glacier, Cook Inlet, Alaska
The Alaska Division of Geological & Geophysical Surveys (DGGS) and U.S. Geological Survey (USGS) are implementing ongoing programs to characterize the petroleum potential of Cook Inlet basin. Since 2009 this program has included work on the Mesozoic stratigraphy of lower Cook Inlet, including the Middle Jurassic Tuxedni Group between Tuxedni...LePain, David L.; Stanley, Richard G.

Geologic maps of the eastern Alaska Range, Alaska (1:63,360 scale)
This report provides a description of map units for a suite of 44 inch-to-mile (1:63,360-scale) geologic quadrangle maps of the eastern Alaska Range. This report also contains a geologic and tectonic summary and a comprehensive list of references pertaining to geologic mapping and specialized studies of the region. In addition to the geologic maps...Nokleberg, Warren J.; Aleinikoff, John N.; Bond, Gerard C.; Ferrians, Oscar J.; Herzon, Paige L.; Lange, Ian M.; Miyaoka, Ronny T.; Richter, Donald H.; Schwab, Carl E.; Silva, Steven R.; Smith, Thomas E.; Zehner, Richard E.
Qualitative assessment of selected areas of the world for undiscovered sediment-hosted stratabound copper deposits: Chapter Y in Global mineral resource assessment
A qualitative mineral resource assessment of sediment-hosted stratabound copper mineralized areas for undiscovered copper deposits was performed for 10 selected areas of the world. The areas, in alphabetical order, are (1) Belt-Purcell Basin, United States and Canada; (2) Benguela and Cuanza Basins, Angola; (3) Chuxiong Basin, China; (4) Dongchuan...Zientek, Michael L.; Hammarstrom, Jane M.; Johnson, Kathleen M.; Zientek, Michael L.; Wintzer, Niki E.; Hayes, Timothy S.; Parks, Heather L.; Briggs, Deborah A.; Causey, J.

Architecture and evolution of an Early Permian carbonate complex on a tectonically active island in east-central California
The newly named Upland Valley Limestone represents a carbonate complex that developed on and adjacent to a tectonically active island in east-central California during a brief interval of Early Permian (late Artinskian) time. This lithologically unique, relatively thin limestone unit lies within a thick sequence of predominantly siliciclastic...Stevens, Calvin H.; Magginetti, Robert T.; Stone, Paul
Regional implications of new chronostratigraphic and paleogeographic data from the Early Permian Darwin Basin, east-central California
The Darwin Basin developed in response to episodic subsidence of the western margin of the Cordilleran continental shelf from Late Pennsylvanian (Gzhelian) to Early Permian (late Artinskian) time. Subsidence of the basin was initiated in response to continental truncation farther to the west and was later augmented by thrust emplacement of the...Stevens, Calvin H.; Stone, Paul; Magginetti, Robert T.
Stratigraphy and paleogeographic significance of a Late Pennsylvanian to Early Permian channeled slope sequence in the Darwin Basin, southern Darwin Hills, east-central California
The complex stratigraphy of late Paleozoic rocks in the southern Darwin Hills consists of regionally extensive Mississippian and Early to Middle Pennsylvanian rocks overlain by latest Pennsylvanian to Early Permian rocks, herein called the Darwin Hills sequence. Deposition of this latter sequence marked the beginning of the Darwin Basin. In...Stevens, Calvin H.; Stone, Paul; Magginetti, Robert T.; Ritter, Scott M.
Petrology and reservoir quality of the Gaikema Sandstone: Initial impressions
The Division of Geological & Geophysical Surveys (DGGS) and Division of Oil & Gas (DOG) are currently conducting a study of the hydrocarbon potential of Cook Inlet basin (LePain and others, 2011). The Tertiary stratigraphic section of the basin includes coal-bearing units that are prolific gas reservoirs, particularly the Neogene...Helmold, Kenneth P.; Stanley, Richard G.
The estimated value of mineral production increased in the United States in 2014, despite the decline in price for most precious metals, the U.S. Geological Survey announced today in its Mineral Commodity Summaries 2015.
Two new U.S. Geological Survey publications that highlight historical hydraulic fracturing trends and data from 1947 to 2010 are now available.
SPOKANE, Wash. — In cooperation with the Polish Geological Institute — National Research Institute, U.S. Geological Survey scientists have published a new assessment of copper resources in Poland and Germany. This investigation is part of the U.S. Geological Survey’s Global Mineral Resource Assessment.
Energy development in the Williston Basin oil production area of Montana and North Dakota, which includes the Bakken and Three Forks Formations, has not affected shallow groundwater quality, according to a recently published study in the journalGroundwater.
Citizens should not be alarmed if they see a low-flying helicopter towing a large wire-loop contraption hanging from a cable in the Poplar, Montana area during the next couple of weeks.
Last year, the estimated value of mineral production in the U.S. was $74.3 billion, a slight decrease from $75.8 billion in 2012. According to the U.S. Geological Survey’s annual Mineral Commodity Summaries 2014 report, the 2013 decrease follows three consecutive years of increases.
U.S. Geological Survey scientists will conduct a comprehensive, high-resolution airborne survey to study the rock layers under parts of Washington, Franklin and Crawford counties. Instruments on the helicopter will collect information about the underground geology and mineral deposits of the region.
Akutan Island, in Alaska’s east-central Aleutian Islands, hosts the City of Akutan and is home to the largest seafood production facility in North America. It also hosts Akutan Volcano, one of the most active volcanoes in the U.S.
The U.S. Geological Survey estimates 896 million barrels of conventional, undiscovered oil and 53 trillion cubic feet of conventional, undiscovered non-associated gas within NPRA and adjacent state waters.
